MPO trunk cable BlueOptics GRD3PBE — 3 m OM4 multimode, 12‑core, LSZH, Type B

BlueOptics GRD3PBE — 3 m OM4 multimode MPO trunk cable with 12 cores and Type B polarity is a pre-terminated fiber assembly designed for short-reach high-density network environments. The 3‑meter length and OM4 multimode fiber support elevated bandwidth and modal performance for 40/100GbE links and other high-speed interconnects. The low-smoke, zero-halogen (LSZH) jacket decreases smoke and toxic gas emission in the event of a fire, making the cable suitable for use in data centers and other indoor installations where fire safety is a priority.

Advantages

This MPO trunk cable offers 12-core multimode connectivity with Type B polarity to match equipment and patch panel wiring schemes. The OM4 fiber grade provides improved bandwidth and lower modal dispersion compared with lower-grade multimode fibers, supporting common short‑reach multimode applications. The pre-terminated MPO ends reduce installation time and minimize field splicing, while the LSZH outer jacket improves safety in enclosed spaces.

Suitable for

• Data center trunking between MPO/MTP patch panels
• High-density multi-fiber backbone links
• Short-reach 40GbE and 100GbE multimode connections
• Cross-connects in telecommunications rooms and equipment racks

When it may not be suitable

This 12-core OM4 multimode trunk cable is optimized for short‑reach multimode networks; it is not intended for long-distance singlemode links or carrier long‑haul applications. It also assumes Type B polarity; installations that require Type A or Type C polarity will need a different trunk or reconfiguration at the patching side.

Key specifications

• Fiber type: OM4 multimode
• Core count: 12 cores
• Polarity: Type B
• Length: 3 meters
• Jacket material: LSZH (Low Smoke Zero Halogen)
• Connector type: MPO/MTP multi-fiber connectors (pre-terminated)

How to use

Install the pre-terminated MPO trunk cable by routing it between MPO/MTP-compatible patch panels or cassettes. Ensure proper guidance through cable trays or containment to avoid sharp bends and maintain the manufacturer's minimum bend radius. Verify polarity and connector orientation before final patching, then secure panels and perform optical loss testing or certification to confirm insertion loss and channel performance meet system requirements.

What to consider before purchase

• Verify that your patch panels, cassettes or transceivers are MPO/MTP compatible and expect Type B polarity.
• Confirm that OM4 multimode performance and the 3 m length match your link budget and physical layout.
• Check routing space and bend radius requirements for multimode fiber to prevent excess attenuation.

Usage recommendations

Handle connectors using protective caps when not in use, perform end-face inspection and cleaning before mating, and document the polarity and test results. For predictable performance in 40/100GbE short-reach links, keep channel components consistent with OM4 multimode specifications and use certified testing equipment after installation.
